+# Lab Test Revenue - SSMM
+
+> Total revenue from lab test charge items linked to issued/balanced invoices
+
+## Purpose
+
+Returns the total lab test revenue at SSMM by summing `total_price` of charge items whose `charge_item_definition` belongs to one of the lab test resource categories (`category_id IN (49, 50, 51, 52)`) and which are linked to a settled invoice.
+
+## Parameters
+
+| Parameter | Type | Description | Example |
+|-----------|------|-------------|---------|
+| `DATE` | DATE | Filter by date range (typically `inv.created_date` or `ci.created_date`) | `inv.created_date BETWEEN '2026-05-01' AND '2026-05-04'` |
+
+---
+
+## Query
+
+```sql
+SELECT 
+    COALESCE(SUM(ci.total_price), 0) AS total_revenue
+FROM emr_chargeitem ci
+JOIN emr_chargeitemdefinition cid ON ci.charge_item_definition_id = cid.id
+JOIN emr_resourcecategory rc ON cid.category_id = rc.id
+JOIN emr_invoice inv ON ci.paid_invoice_id = inv.id
+WHERE rc.id IN (49, 50, 51, 52)
+  AND ci.deleted = FALSE
+  AND inv.deleted = FALSE
+  AND ci.status IN ('paid', 'billed')
+  AND inv.status IN ('issued', 'balanced')
+  --[[AND {{DATE}}]]
+;
+```
+
+
+## Notes
+
+- Hardcoded to `rc.id IN (49, 50, 51, 52)` — the lab test resource categories. Update if these IDs change or new lab categories are added.
+- `COALESCE(SUM(...), 0)` ensures the result is `0` instead of `NULL` when no rows match.
+- Metabase-specific filters (`[[...]]`) allow dynamic filtering in dashboards.

+# Lab Test Count - SSMM
+
+> Total count of lab test charge items
+
+## Purpose
+
+Returns the total number of lab tests at SSMM by counting charge items whose `charge_item_definition` belongs to one of the lab test resource categories (`category_id IN (49, 50, 51, 52)`) 
+
+## Parameters
+
+| Parameter | Type | Description | Example |
+|-----------|------|-------------|---------|
+| `DATE` | DATE | Filter by date range (typically `ci.created_date`) | `ci.created_date BETWEEN '2026-05-01' AND '2026-05-04'` |

+## Query
+
+```sql
+SELECT 
+    COUNT(ci.id) AS total_tests
+FROM emr_chargeitem ci
+JOIN emr_chargeitemdefinition cid ON ci.charge_item_definition_id = cid.id
+JOIN emr_resourcecategory rc ON cid.category_id = rc.id
+WHERE rc.id IN (49, 50, 51, 52)
+  AND ci.deleted = FALSE
+  AND ci.status IN ('paid', 'billed', 'billable')
+  --[[AND {{DATE}}]]
+;
+```
+
+## Notes
+
+- Hardcoded to `rc.id IN (49, 50, 51, 52)` — the lab test resource categories. Update if these category IDs change or new lab categories are added.
+- Only active (`ci.deleted = FALSE`) charge items are included.
+- Metabase-specific filters (`[[...]]`) allow dynamic filtering in dashboards
